Screen reader applications do not read the alt tags in the pdf

Text to screen reader applications do not read the alt tags in the pdf my app creates. I use Aspose.PDF to convert my view in MVC C# application to pdf.
I read the Aspose web page on Accessibility but that only shows adding elements through C# but I want to add html to the view for Accessibiltiy. Accessibility and Tagged PDFs|Aspose.PDF for .NET
